Russian President Vladimir Putin is scheduled to chair a session of the Collective Security Council of the Collective Security Treaty Organization (CSTO) in Moscow on November 11, according to a statement from the Kremlin press service. The summit will cover cooperation measures, strengthen the CSTO’s collective security system, and address urgent international and regional issues. It will also involve the signing of a number of multilateral documents and the adoption of a decision to transfer the organization’s chairmanship from Russia to Tajikistan effective January 1, 2027.
Background
The CSTO, founded in 2002, is a military alliance that includes Russia, Belarus, Kazakhstan, Kyrgyzstan, Armenia, and Tajikistan. Its Collective Security Council is the main decision‑making body, and the presidency has traditionally been held by the Russia. The organization’s charter allows for a formal transfer of the chairmanship to another member state after its term ends. In this case, Tajikistan will assume the role on January 1, 2027, marking a significant shift in the alliance’s leadership structure.
President Putin’s briefing said that the discussions would revolve around "key aspects of cooperation and measures to further strengthen the CSTO’s collective security system," emphasizing the continued importance of the alliance in the region’s security architecture. The plan also includes the adoption of decisions on compelling issues that the members deem urgent, as well as the signing of multilateral documents that further bind the allies together.
Potential Changes to Membership Rules
In unrelated statements, several Armenian news outlets reported that the November 11 summit might address Armenia’s voting rights within the CSTO. According to a report from 1in.am, leaders of the CSTO are expected to gather in Moscow and could consider suspending Armenia’s voting rights. The suggestion raises questions, because Armenia has been an active participant since 2008 but has faced criticism from other members over its ongoing conflict with Azerbaijan.
While the report did not specify who would propose the suspension or the exact grounds for such a move, observers note that Armenia’s relationship with the alliance has been strained by the Nagorno‑Karabakh conflict. The Armenian government has indicated it would prefer to maintain its voting status, citing the strategic partnership as integral to its national security.
Open Questions
The summit’s agenda is still largely unannounced, leaving several key issues unresolved. Journalists and analysts from TASS have highlighted that the talks will cover "urgent international and regional issues," but no specific topics have been disclosed. Some experts speculate that the debate might connect to the current tensions in the South Caucasus, the evolving security posture of the U.S. and NATO in the region, or the need to coordinate responses to terrorism and cyber threats.
Another point of uncertainty is the content and scope of the multilateral documents that will be signed. The CSTO has issued a series of joint statements and agreements in previous meetings, but which new treaties or protocols will be activated remains unknown. The lack of detail fuels speculation on whether the organization might introduce new protocols on intelligence sharing, joint military exercises, or rapid deployment forces.
Finally, observers are uncertain how the transition of chairman to Tajikistan will take effect. The current charter allows for a handover procedure, but the mechanics and timing—especially as the summit occurs two years before the official change—are not yet clarified. Analysts from Russian defense think‑tanks anticipate that the summit could serve as a formal rehearsal for the handover, with Tajik officials likely to take a prominent position in key sessions.
With the date set for November 11, all CSTO members are preparing to travel to Moscow, and news agencies worldwide are tracking the developments as they unfold. The summit promises to shape not only the alliance’s future leadership but also the ongoing dialogue over regional security and member state sovereignty.
